DHRF系列电动衬氟O型球阀是旋转切断型球阀它由ARSOTA阿斯塔智能型电动执行机构和衬氟塑球阀两部分组成。由于该阀内腔及球体均采用高压注塑工艺，衬有耐腐蚀、耐老化的氟塑料FEP(简称F46)或PTFE(简称F4)，故具有可靠的耐腐蚀性和密封性。能广泛适用于化工、石油、冶金、医药、电力等工业部门，实现对生产过程中酸、碱等强腐蚀介质的调节或切断。
DHRF O-series electric fluorine spin cut-off valve is a valve which consists of ARSOTA Astana intelligent electric valve actuators and fluorine plastic composed of two parts. As the valve cavity and the sphere are using high-pressure injection molding process, lined with corrosion-resistant, anti-aging fluorine plastic FEP (referred to as F46) or PTFE (referred to as F4), it has the corrosion resistance and reliable sealing. Can be widely used in chemical, petroleum, metallurgy, medicine, electricity and other industrial sectors, to achieve the production process, acid, alkali and other strong corrosive media regulation, or cut off.
